How to place a simple interrupted suture
Other platforms explain it with text and video. In Making Synapses you practice it on the patient.
The goal is edges that meet and turn slightly outward, without tension.
Step by step
Prepare
Consent, anesthesia, irrigation, explore the wound, sterile field. [1]
Enter at 90 degrees
Needle perpendicular to the skin, a few mm from the edge. [1]
Equal bites
Same depth and distance from the edge on both sides; follow the needle curve. [1]
Evert
Wider at the base than at the surface, so edges turn out. [1]
Instrument tie
Square knots (three or more throws), knot to one side. [1]
Spacing
Similar to the bite distance; dressing, tetanus status, removal date. [1]
Common errors
- Edges inverted.
- Too tight (ischemia).
- Unequal bites.
Practice it in Making Synapses
In Making Synapses you do this on the patient, not on paper: every step goes on the checklist with a score, and in Teach mode Blocky tells you what comes next.
